WATCH: Unsolved Mysteries Promises More Unsettling, Unexplained Investigations in Volume 3 Trailer

Unsolved Mysteries has more in store.

The iconic docuseries returns for Volume 3 on October 18, and the trailer for the upcoming season promises to unsettle viewers and hopefully bring some closure to its subjects.

"We're always looking for answers," says one man. "We've only begun to scratch the surface." As the subjects plead for answers about what happened to their loved ones, Unsolved Mysteries unravels these strange cases one episode at a time. 

This season will explore "unexplained deaths, baffling disappearances, and bizarre paranormal activity", spotlighting cases including the death of an 18-year-old volleyball star, lights hovering over Lake Michigan, the murder of a beloved single father, a college student's unexplained disappearance, paranormal activity on a Navajo reservation, and more.

There will be nine episodes in total, each featuring a different mystery.

The cases presented in the first two seasons elicited a massive viewer response, leading to 5,000 tips and prompting the FBI to reopen their investigation into Alonzo Brooks' death. 

Unsolved Mysteries Volume 3 debuts on Netflix October 18 with three new episodes. Subsequent installments will premiere October 25 and November 1.
